I transfer the PDF to Google drive. This is just an easy way to get them onto my multiple Android devices. I download the PDF onto the SD card of any device in want to read it on. I use ebookdroid to read the PDF. It remembers exactly where I was. It options to auto crop, dark more etc. To read on multiple devices I track every PDF I'm reading in a Google spreadsheet. This also has the nice side effects of tracking all the PDF's I'm reading, and being able to track my reading progress over time.
